If you've watched 'Stranger Things' yet, you'll already be aware that Mike is one of the best characters in the show. (Alright, then - second best, after Dustin.)

The actor who plays him, Finn Wolfhard, also happens to be a bit of a boss on the guitar (as well as having a pretty cool name).

He also has fairly good taste in music for his tender 13 years, posting a video of himself playing the riff from Nirvana's 'Lithium' on Twitter - although he really should have learned The Clash's 'Should I Stay or Should I Go' first.
